Thank you for testing, it is highly appreciated.

I will try to build using the docker image as I'm only getting problem
with host-libzlib, even for a clean build.

I will add this for the next patch version

ifeq ($(BR2_ARM_CPU_ARMV6), y)
CRIU_MAKE_ENV += SUBARCH=armv6
else ifeq ($(BR2_ARM_CPU_ARMV7A), y)
CRIU_MAKE_ENV += SUBARCH=armv7
else ifeq ($(BR2_ARM_CPU_ARMV7M), y)
CRIU_MAKE_ENV += SUBARCH=armv7
else ifeq ($(BR2_ARM_CPU_ARMV8A), y)
CRIU_MAKE_ENV += SUBARCH=armv8
else ifeq ($(BR2_ARM_CPU_ARMV8M), y)
CRIU_MAKE_ENV += SUBARCH=armv8
endif

But the Makefile defaults to armv7, so I do not think it make any
difference for bootlin-armv7-glibc.
